How to Make It

Step 1

Preheat oven to 400°. Melt butter with oil in a large skillet over medium-high heat. Add onions, sugar, and salt; cook, stirring occasionally, 8 minutes or until onions soften and just begin to turn golden. Reduce heat to medium, and cook, stirring often, 20 minutes or until onions turn deep golden brown. Stir in vinegar, scraping bottom of skillet to deglaze pan. Cook, stirring often, until vinegar is reduced by half. Stir in thyme.

Step 2

Cook bacon in a large skillet over medium-high heat 8 to 10 minutes or until crisp. Drain on paper towels; finely crumble.

Step 3

Combine cheese and next 3 ingredients in a medium bowl. Stir in onions and bacon. Transfer to a 2-cup baking dish.

Step 4

Bake 20 minutes or until mixture bubbles and top is lightly golden.

I haven't yet made this, but I have to ask why the sugar?  Being insulin dependent diabetic, I have to ask just how important it is to the recipe.

Delicious! Much of this can be made ahead and just popped into the oven at the last minute.

This was really good although I did make a few modifications. cooked the bacon first then cooked the onions in the bacon fat. I used light sour cream and light mayo. Really great flavor. Will definitely make again.

Made this for Thanksgiving appetizer using caramelized onions I had made in October from Walla Walla Sweets in the crockpot, then froze, so helped out on time, but did add some add'l moisture, resulting in an extra 15 min or so in the oven. However, it was the one appetizer that everyone kept coming into the kitchen to tell me how much they loved it! It was also exceptionally easy, and with the exception of the gruyere, all pantry staples, even w/o frozen onions, and will be on my list of things to make again!
